The secrets of the McLaren-Honda package

The first proper test of the Honda-powered McLaren in Abu Dhabi was far from successful, but there were still plenty of interesting developments, as CRAIG SCARBOROUGH explains

The public debut of the rekindled McLaren-Honda Formula 1 partnership last month offered the first glimpses of the Japanese manufacturer's new engine.

From what we've seen at the post-season Abu Dhabi F1 test and the team's filming day at Silverstone prior to that, the Honda power unit appears to be at least partly inspired by developments we saw from the other manufacturers in 2014.
